SOLE-TRIMMING MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 688,815, dated December 17, 1901.

Application filed February 23, 1899. Serial No. 706,561. (No model.)

To all whom, it may concern:

Be it known that I, EDWIN E. ANGELL, of Somerville, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Boot or Shoe Trimming Machines, of which the following is a specification.

This invention relates to machines espe cially adapted for trimming and randing the soles of boots and sh0es,and especiallyadapted for rough-rounding and randing the heelseats of boots and shoes, by which is meant trimming oif the surplus stock of the sole around the heel, and by randing is meant r5 trimming the upper-edge between the upper side of the sole and thecounter of the heel or between the sole and the upper.

My invention consists of certain novel features hereinafter described, and particularly 2o pointed out in the claims.

In the accompanying drawings, which illustrate a construction embodying my invention, Figure l is a front view of a portion of a boot and shoe trimming machine. Fig. 2 is a view of the lower part of the machine with the lower part of the basein section. Fig. 3 is a side view of a portion of the sole-guard and carrier in section. Fig. 4 is a perspective View of the sole-guard carrier. Fig. 5 is a perspective view of the bell-crank lever hereinafter described. Fig. 6 is a sectional view of the front end of the carrier-spindle. Fig. 7 is a side view of the improved sole-guard and holder. Fig. 8 is a top plan view of the soleguard. Fig. 9 is a plan view of the sole-guard and adjustable ring. Fig. 10 is a cross-sectional View through the sole-guard. Fig. 11 is a cross-sectional view through the adj ustable ring. Fig. 12 is a plan view of the sole 4o guard and sole-guard holder. Fig. 13 is a top plan view of the machine, showing my improvements applied thereto.

Like letters of reference refer to like parts throughout the several views.

5 A represents a yoke-shaped casting provided with two arms A, which carry at their upperends the bearings B for the cutter-shaft A The carrier C is provided with a hub C, around which is located the sole-guard holder D, and which on the extreme ends of the arms D is provided with a screw-thread I), on which is secured the adjustable ring E, provided on its outside surface with the recess E, in which the lip F of the sole-guard F rests and upon the ring E the sole-guard F revolves. The sole-guard holder D is secured to the soleguard carrier by a set-screw A and the adjust able ring E is secured in its adjusted position by the set-screw D The sole-guard F is corrugated on its outer surface, as shown at F for the purpose of providing a roughened. surface in order to grip the leather in the operation of the machine. The lip F prevents the soleguard from being moved off of the ring E and also prevents the dirt from working into the bearings. This lip is formed after the sole-guard F has been placed on the ring E, and said lip is formed by rolling the lower part of the sole-guard into the annular recess E of the ring E. The sole-guard is made ro- 7o tatable in order to move with the work as the work moves around the cutter, and thereby reduces the friction over a construction in which the sole-guard is made permanent, and, further, it is obvious that by being rotary the labor of the operator is reduced." Oil is applied for lubricating by dropping it into the recess E, and from said recess the oil works out through the slots Eiwhich lead from said recess E, and lubricates the sole- 8o guard. Loosely mounted on the shaft A is an extension-blade holder Gr, provided at its forward end with the blades G, which featheredge the bottom of the sole. On the rear end of the extension-blade holder is the threaded nut H, which is screwed upon the blade-holder up to its shoulder H and holds the said holder with relation to the sole-guard carrier O. In the sole-guard carrier C is mounted the hollow screw I, which is mounted upon the carrier-spindle J, which extends rearwardly, and around its center is provided the spring K, which bears against the forward end of the spindle J at K and at its rear end bears againstthe casting at K and the object of said spring is to throw forward the sole-guard carrier and connecting parts which automatically provides proper pressure for the sologuard against the work. The spindleJpasses I00 rearwardly through the fork L of the bellcrank lever L, which is pivoted at L to the nected the rod L, which extends downwardly and is connected to an arm M,fast on the shaft M. The yoke N has at its lower end the guide-pin N,which,as shown, islocated in the hole N in the casting for the purpose of guiding and preventing the spindle J from turning around while the sole-guard carrier is being adjusted by means of the screw L'the screw I being secured firmly in its adjusted position bythe set-screw J, screwing into the opening J of the spindle J. The yoke Nis secured to the spindle J by means of the pin N to hold them rigid to one another. On the extreme lowerend of the sole-guard carrier is mounted aguide-stud O ,which moves in the yoke-castingA for the purpose of holding the carrier 0 in its proper working position. On the rockshaft M is fiited fast a treadle M and upon movement. being imparted thereto by the foot of the operator the spring (),which is attached to the arm M at one end and at its other end to any desirable part or" the base, yields to the movement of said rock-shaft. By means of the treadle M rod L bell crank lever L, and spindle J the sole-guard carrier 0 and solegnard F are moved rearwardly for the introduction of the work to the cutters, which in practice are mounted upon the tapered end A of the cutter-shaft A in the manner illustrated in United States Patent to Vose, No. 560,825,

moval of the foot the sole-guard is pressed forward by the spring J in contact with the sole, and the sole is held in its proper working position between the sole-guard, cutter,

and cutter-shield. The sole-guard F being mounted as described revolves with the Work when'it is being acted on by the cutters, thereby preventing injury to the work. The hollow screw I is for the purpose of regulating the pressure of the spring K for the adjustment oldiilerent variations of thickness of soles, so that by this arrangement the same pressure may be obtained for thick soles as for thin soles. i

I do not claim in this application the construction ofthe extension-blade holder, as the same forms the subject-matter of another application filed by me simultaneously herewith and having the serial number 706,563.

I do not limit myself to. the arrangement and construction shown, as the same may be varied Without departing from the spirit of my invention.

Having thus ascertained the nature of my invention and set forth a construction embodying the same, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. In a boot and shoe trimming machine, a sole-guard carrier, a sole-guard holder on said carrier, an adjustable ring on said holder, and a sole-guard movably mounted on said ring and adapted to move with the work in the operation of the machine.

2. In a boot and shoe trimming machine, a

sole-guard carrier, a sole-guard holder on said carrier, an adjustable ring on said holder, and a sole-guard having an inwardly-turned lip on its inner edge adapted to fit into said recess on said ring and movably mounted on said ringand adapted to move with the work in the operation of the machine.

3. In a boot and shoe trimming machine, a carrier provided with a hub, a holder mounted on said hub, a ring adjustable on said holder and provided with an annular recess, a soleguard rotatable on said ring and having an annular lip bent into said recess for holding said guard in place.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 15th day of February, A. D. 1899.
